Abstract (en)
[origin: EP0347259A2] A torsional vibration absorbing device in a clutch disc assembly comprises a drive plate having means releasably coupled with a driving torque source to be rotatingly driven by the output torque of the driving torque source while it is coupled therewith, a first hub member frictionally associated with the drive plate for rotation therewith, an idler member associated with the first hub member for rotation therewith, a first torsional vibration absorbing mechanism provided between the first hub and the idler member for permitting relative angular displacement therebetween within a first predetermined angular range, the first torsional vibration absorbing mechanism including a first resilient member having a first resilient characteristics, a second hub member rigidly associated with an output shaft through which a driving torque of the driving torque source is transmitted to an external load, and frictionally associated with the first hub member so as to be rotatatingly driven according to rotation of the latter, a second torsional vibration absorbing mechanism interposed between the first and second hub members for permitting relative angular displacement between the first and second hub members within a second predetermined angular range which is smaller than the first predetermined angular range, the second torsional vibration absorbing mechanism including a second resilient member having a second resilient characteristics which is smaller than the first resilient characteristics. In addition, the torsional vibration absorbing means includes a hardened layer provided on at least one of mating surfaces of the first and second hub members.
